Technique for packing, the wallboard for being mainly used for the assembled architectures such as residential houses, office building make.
Background technology
Building industrialization and housing industrialization and Urbanization Construction require actively to promote prefabricated construction.For building
Building enclosure, it is exactly the assembling degree of wall to examine the key index of building industrialization level.Promote and apply assembled light
Heat insulating type concrete Side fascia meets the industrial policy of national green building and building energy conservation, is that building trade realizes sustainable development
Open up the important content of strategy.Polyphenyl foam particle (EPS) wall heat insulation material is with water absorption rate is small, heat insulation property is good, of equal value
The advantages that lattice are cheap, easy for construction is the developing direction of China's building energy conservation materials for wall.
Since EPS particle surfaces are smooth, there is apparent hydrophobicity, the adhesive property between cement-based material is excessively poor,
It causes EPS thermal insulation material intensity low, limits large-scale popularization application of the EPS heat-insulation wall plates in building field, however do not have also at present
There is relevant solution.Therefore, the pretreatment technique for packing for researching and developing EPS particles wraps up one layer in smooth EPS particle surfaces
Fast hard, high-strength shell layer is obviously improved the bonding of particle and cement-based material while improving EPS particle self-strengths
Performance increases substantially the intensity of assembled EPS heat-insulation wall plates, for accelerating the development of China's assembled architecture, improves building
The effect of heat preservation energy-saving has most important theories and realistic meaning.
Invention content
The present invention is directed to EPS particles existing in the prior art and cement-based material bad adhesion, resistance to compression after wallboard is made

The strong magnesium phosphate cement shell layer of a floor height has been wrapped up on EPS particles out, surface, has intensity high, viscous with cement-based material
The good feature of performance is tied, the intensity of assembling thermal-insulating wall board can be significantly improved, is suitable for requiring heat preservation, heat-insulated, sound insulation high
The buildings such as house, office building in.
The specific technical solution of the present invention is as follows:
A kind of assembling thermal-insulating wall board EPS pretreatment of particles technique for packing, the technology is in five steps of processing procedure point
Suddenly:
The first step:2 parts of surfactants and 100 parts of water are uniformly mixed into the mixture of surfactant and water;
Second step:The mixture of surfactant and water is sprayed on EPS particle surfaces, EPS particles is made to be sufficiently humidified so as to;
Third walks:Magnesium phosphate cement is stirred into flowing water slurry body according to match ratio:
4th step:EPS after moistening is poured into blender to be stirred, magnesium phosphate cement slurry is sprayed during stirring
Body controls the thickness of wrapping layer, stir and is sprayed to EPS particles completely by phosphorus by spraying the amount of magnesium phosphate cement slurry
It discharges after sour magnesium cement package;
5th step:It conserves 6 hours at ambient temperature, after magnesium phosphate cement condenses hardening completely, the shape outside EPS
At the wrapping layer that uniform, thickness is 1~2mm.
Contain carboxylic acid, sulfonic acid, sulfuric acid, amino or amido polar hydrophilic group in the molecular structure of the surfactant,
After being mixed with water and moistening EPS particle surfaces, the hydrophilic ability of EPS can be improved, improves the bonding with magnesium phosphate cement.
The magnesium phosphate cement is a kind of cement of high-early-strength, and setting time can be controlled within 30 minutes, after hardening
Intensity reaches 60MPa intensity, rapidly can be wrapped to form high-strength shell in smooth, hydrophobic EPS extra-granulars;
The magnesium phosphate cement has good adhesive property with Portland cement, and by this technology, treated
EPS particles, can significantly improve the compression strength of assembling thermal-insulating wall board, and magnesium phosphate cement includes as follows by mass percentage
Substance:
Compared to the prior art the present invention, has the following advantages that:
(1) technique for packing is pre-processed using EPS provided by the invention, it can be rapidly in smooth, hydrophobic EPS particles
Periphery package last layer magnesium phosphate cement shell, compared with before package, the EPS particles after package have higher cylindrical compress strength,
With Portland cement and with good caking property, to significantly improve the intensity of assembled EPS heat-insulation wall plates;
(2) magnesium phosphate cement used in the present invention is conventional building material, and raw material are easy to get, and cheap;
(3) present invention's is technically simple easy, fully utilizes a large amount of silicon ashes, flyash equal industrial residue, also has green
The characteristics of colour circle is protected.
